Pushing the sides of the carrier in and tightening further can prevent any strap vibration that can occur (and is really annoying). Wonderful product, original Nike product. If you want all you play station accessories in one place then this is the product for you. And the comfort and fit are great. Don?t buy from here It was always annoying trying to figure out which earhook goes on which AirPod. The Cons:- For whatever reason, this Eufy does not run as long. Overall sound quality is not as good as similarly priced Master & Dynamics or even the also bass-heavy Bose. Ive used them around a construction area and for the most part they blocked out the majority of the outside noise. Just increased quantity.
